Glai Baan has managed to push all the other Thai restaurants I like down a slot and claim first place with me. I like that they offer items you can't get at other Thai eateries. Their specialty is Thai street food but they have things like pad Thai for the more vanilla taste buds.
My favorite item has to be those darn pork dumplings. They are very similar to the xiao long bao you can get at Chinese soup dumpling restaurants. They were so flavorful, so tender that my party and I ordered another plate of them. I also had the very aromatic Thai sausage. We did order pad Thai which was very tasty. I also had the son-in-law eggs, which are boiled and fried. They were good but I don't think I would pay money for just ONE egg.
The ambience is really like every other Thai restaurant in Phoenix. Pictures of the king (RIP), simple wooden chairs and tables and loud table cloths for the patio. Anyway, with the way they cook, I don't care what the decor is. Looking forward to a return visit!
